SAW-GUARD.

Specification of Letters Patent.

Patented March 27, 1906.

Application filed November 17, 1905. Serial No. 287,763.

To rill/1 1072.071), it may concern:

Be it known that I, JAooB GEO. HILL, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented new and useful Improvements in Saw-Guards, of which thefollowing is a specification.

This invention relates to improvements in saw-guards.

The object of the present invention is to simplify and improve theconstruction of saw-guards, and to provide a simple, inexpensive, andefficient device adapted to be readily applied to a saw and capable ofprotecting both the saw and the operator.

A further object is to provide a device that may be readily alined withthe saw and one in which when cutting narrow strips the strip will beprevented from catching or being thrown forward.

The invention consists of certain novel features, which will be morefully described in the following specification and clearly illustratedin the accompanying drawings, in which- Figure 1 is a side elevation ofa table, showing my device in position. Fig. 2 is a plan view. Fig. 3 isa front edge view.

The numeral 1 designates the table, and 2 a circular saw. The sawoperates in the usual slot 3 in the table.

The numeral 4 designates the spreader, and this spreader passes throughthe slot 3. The lower end 5 of the spreader is set at right angles tothe body and is provided with one or more elongated openings 6. Bolts 7pass through the table and through these openings and are provided withnuts 8. By means of this arrangement longitudinal adjustment is secured.The upper end 9 of the spreader is bent forward at an angle to the bodyand is provided with a series of holes 10.

The numeral 11 indicates the guard proper or hood. This hood is formedin a single piece, preferably of sheet metal, and its rear end 12 issplit longitudinally, and the two portions are bent so that they lie atright angles to the hood portion, though approximately on the sameplane. The hood portion 11 is bent to approximately a semicircle incross section. The rear portion 12 is adapted to receive the upper end 9of the spreader and one of the bent sides thereof to lie against eitherside of the spreader. These portions 12 are provided with one or moreholes 14 and are adapted to be adjustably secured to the spreader bymeans of pins or screws 20 passing through the holes in both thespreader and the said ends 12 of the guard. A pawl 15 is pivoted at apoint 16 to the top of the spreader 9, and this pawl is adapted to fallinto engagement with and hold in position against the table the strip ofwood as it is being sawed from the timber. The pawl is so arranged thatthe piece so cut cannot rise or be thrown forward, as it will be alwaysheld in position against the table, though it will be free to pass inthe proper direction.

In applying my device the spreader is passed through the slot on thetable from below, and the right-angled end thereof is securely bolted tothe table by means'of the bolts 7. This will secure it solidly inposition and assure its rigidity. The hood is then placed in position onthe spreader and secured by means of the screws 20. The pawl is alsoplaced thereon by means of the screw 16.

My improved fastening device insures ab solutely against the hooddescending onto the saw and guarantees permanent adjustment.

Having thus fully described my invention, what I claim is A saw-guardcomprising a spreader having a rightangled'lower end, elongated openingsin said angled end, bolts passing through said end, a series ofperforations in the upper end of said spreader, a hood-piece having itsrear end split longitudinally, both portions of said split end beingbent to lie parallel with each other, said split ends havingperforations adapted to register with one or more of the perforations inthe spreader, screws passing through both the spreader and said splitend, a curved hood formed on the forward end of said hood-piece adaptedto extend over the saw, and a loosely-pivoted pawl attached to the topof said spreader.

In testimony whereof I afliX my signature in presence of two subscribingwitnesses.

JACOB GEO. HILL.
